CONCEALEI) FASTENING FOB WALL-FIXTURES.

Specification of Letters Patent.

Patented May 27, 1919.

Application filed November 24, 1915. Serial No. 83,208.

To all whom it may concern:

Be it known that I, ARTHUR J. WEIss, of the town of West Orange, county of Essex, and State of New Jersey, have invented a certain new and useful Improvement in Concealed F astenings for Wall- Fixtures, of which the following is a specification, reference being had to the accompanying drawings, which form a part of the same. 4

An object of my invention is to provide means for aifixing fixtures, such as electric fixtures, to a wall, partition or support in such a manner that the securing means will be concealed, thus doing away with attaching screws, rivets, nails or other unsightly securin elements.

Anot er object of my invention is to provide means for securing fixtures to their supports in such manner that they may be readily removed for any purpose, such as cleaning, repairing-or shifting to another connection.- Other objects of my invention will be apparent hereinafter.

Referring to the drawings,

Fi re 1 is a vertical cross section of an e ectric light fixture embodying my invention;

Fig. 2 is a view showing the back of such fixture in which my improved securing means are'exhibited;

Fig. 3 is 'a side view of a clip used in connection therewith;

Fig. 4 is a plan view of the clip in place over a securing nut or cap.

Referring now in detail to the drawings, 1 represents a fixture plate or shield to which is attached the arms 2, through which electric wires. (not shown) are adapted to run. Securely fixed to the inside of the shield 1, and oflset therefrom, is a clip 3 having serrations 3. This cli is shown to be connected to a screw 4 tting into theoifset 5, the said ofl'set being brazed, cast, welded or otherwise secured to the back of the shield 1.

An outlet box 7 having a fixture stud 8 with a screw thread 9 projecting therefrom is shown, in connection with which the nut or cap 10 is adapted to cooperate, This nut or cap is provided with a projecting portion or flange 11 which extends beyond the spread of the prongs of the clip 3.

pended claim.

In operation the fixture with the clip I va flixed thereto on its reverse side, as shown,

is placed over the nut or cap 10 screwed onto the fixture stud 8 of the outlet box or support 7, the prongs of the clip 3 straddling the said nut or cap 10 between the flange thereof and the outlet box or support. Set-rations 3 are shown on one of the prongs of clip 3. These serrations are made for the purpose of giving the nut a further turn as the clip is being pressed down over it, the serrations pressing against the inside flange of the nut for this purpose, and thus giving the nut a tightening effect. These serrations will also tend to prevent the turning of the securing nut when in place.

. When the double wire system of electric lighting is used in connection with my dematerial. Where the single wiring system is used, such as is described in my application for United States Letters Patent Serial No. 34,825, filed June 18th, 1915, the nut or cap provided is formed of conducting material and becomes part of the negative side of the electric circuit.

In the above description and the accompanying drawings, I have shown a preferable embodiment of my invention, but I do not wish to be confined to the disclosure therein contained, but what I desire to cover by Letters Patent is set forth in the ap- Claim.

In concealed fastenings for wall fixtures, a plate, a bifurcated clip secured at one end to and offset from the back of said plate, the" bifurcated legs of said clip being free, one of said legs being provided with a frictional surface, a securing element adapted to be fitted in a wa1l,.a cap adjustable on said securing element and adapted to cooperate therewith, a flan pro ecting outwardly from said cap, said flange being adapted to fit between the bifurcated legs of the clip and the plate.
